Figure 2. VHF Doppler spectra integrated for two minutes, with spectra plotted for gates 44 through 91 and a height profile of mean velocity, total power, spectral peak, and noise level for 128 gates. Positive Doppler velocity (toward the radar) is to the right of center, each spectra is scaled to its own peak and noise level.

put Radar Processing.” For a given signal-to-noise ratio (SNR), the radar range resolution is dictated by the transmit bandwidth, i.e., 1/T r in (1). The velocity resolution is determined by the duration of coherent integration, i.e., NT in (2). In cases 1 and 3, no Doppler processing is undertaken, mainly because typical

If no radar is detected during the initial 60-second listening period, the AP can begin transmitting beacon management frames on the channel. In Europe, the CAC rules are even more restrictive for the Terminal Doppler Weather Radar (TDWR) channels of 120, 124, and 128.
